Possible acquisitions
The board
APCI-3701
generates the sinusoidal supply voltage and evaluates the
measuring signal.
-
Each channel can be independently acquired (single mode; See Fig. 9-5)
-
The board can acquire the channels in sequences:
n sequences can be carried out; 1
≤
n
≤
65.535 (See Fig. 9-7)
-
n sequences can be divided in k sequences. After acquiring m sequences, the
conversion is stopped. This occurs k times. A new trigger starts the conversion
for m sequences again and so on till the n sequences have been acquired. (n =
k.m See Fig. 9-8)
-
The board can acquire sequences in continuous mode.
Each of this acquisition possibility (programmable by software) is started:
-
through start enable
-
by software trigger (Single software sequence) or
-
by hardware trigger (through the digital input 0).
Delay
A delay time can be set in sequence or continuous mode. It can be set between 2
successive conversion starts or between the end of a conversion and the start of
the next conversion.
The delay time is determined by software through a 16-bit timer (from 0 to 65.535
ms).
